Review: Stared working after just one application. - Started working within a month! We had two experts out to see why our yard never dried out. Both said our septic system was working fine. Even with having the system pumped the yard would not dry up. One application of this and we already have noticed a major change for the better. We just bought a second bottle and hope our problems are behind us. ## Features - SEPTI-FLOW SHOCK DRAINFIELD LINE CLEANER: Septi-Flow Shock, a heavy-duty septic field line cleaner, efficiently cleans and clears septic drain field lines, combating the buildup of excess soaps, detergents, sodium, and sulfate - ELIMINATES BUILDUP: Our septic drain field treatment helps eliminate sodium, phosphate, and sulfate buildup in your septic drain field. It also aids in eliminating locked up and deadpanned soil from soap, sales, and detergent runoff - BIODEGRADABLE SOLUTION: Septi-Flow Shock, scientifically studied and used since 1950, is safe for all septic systems, pipes, plumbing and is biodegradable in the septic tank system - COST-EFFECTIVE: Septi-Flow Shock prevents expensive septic drain field repairs. Check our YouTube videos for detailed instructions on how to use this cost-effective leach field treatment - SEPTI-FLOW SHOCK DIRECTIONS: An average 1,500 gallon septic tank (a 4/3 bed/bath house) start with 4 gallons of product. We recommend pumping the tank prior to treatment. Pour 2 gallons of Septi-Flow Shock into the toilet, tank, distribution box. After 1 week, add 2 more gallons of Septi-Flow Shock. Flush freely with water. Within 2-4 weeks you should see an improvement with the flow. If the septic is completely stopped this product WILL NOT work to address the issue. Salt/sodium/phosphate buildup from soaps, laundry/dishwasher agents, and water softeners (salt buildup) are one of many possible problems could be pipe collapse, roots, septic other potential problems. - FLOW REQUIREMENT: Keep in mind, Septi-Flow Shock will not work on completely stopped septic leach field systems. There must be some movement and flow in your system for our drain field cleaner to work - EASY APPLICATION: Start with 4 gallons of product for slow or sluggish drain fields/septic tanks. We recommend pumping the tank first and then pour 2 gallons of product via the toilet, sink, or drain closest to the septic tank outlet ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005O1WOF4 | | Best Sellers Rank | #48,918 in Health & Household ( See Top 100 in Health & Household ) #32 in Septic Tank Treatments | | Brand | Septi-Flow | | Brand Name | Septi-Flow | | Customer Reviews | 4.2 out of 5 stars 933 Reviews | | Included Components | Septic Drain Field Cleaner | | Item Form | Liquid | | Item Type Name | Septic Drain Field Treatment and Septic Leach Field Repair | | Item Weight | 128 Ounces | | Liquid Volume | 128 Fluid Ounces | | Manufacturer | Nature's Innovation, Inc. | | Model Number | SF1G | | Number of Items | 1 | | Part Number | SF1G | | Product Benefits | Cleans Drain | | Scent | Unscented | | Unit Count | 128 Fluid Ounces | | Warranty Description | We can not guarantee this product as septic systems vary so significantly that there is no one way to diagnose all potential septic problems without direct examination. Our product addresses sodium (salt), phosphate buildup from the use of soaps and detergents in the septic system. This eventually locks the system up from accepting water. Our product addresses this through a chemical reaction.

It will not work if the soil is completely locked up! Septi Flow will not kill the microbes in your septic tank. **Q: How do I know how much Septi-Flow Shock to use?** A: The recommended amount depends on tank size. For most 1,000-1,500+ gallon tanks, add (One) four-gallon pack of Septi-Flow Shock. For slow/clogged systems due to sodium buildup it is best to pump first. For routine maintenance, pumping is not needed. **Q: How long after treatment will I see results?** A: We always recommend pumping your system (unless you are adding the product for maintenance purposes) before adding this product for the best result. Average results occur in 3-6 weeks, but we have seen improvements in 7-10 days. **Q: How do I know this product is what my system needs?** A: To know if Septi-Flow is right for your septic system the best step is having a septic professional assess it on-site. Even if you use Septi-Flow, we recommend pumping the tank first before treatment; unless you're adding it for routine maintenance. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This stuff really works! *by J***R on May 7, 2026* No clog too big for this acid! ### ⭐⭐⭐⭐⭐ Stared working after just one application. *by S***M on July 8, 2025* Started working within a month!

Fields still clear!! *by N***V on March 7, 2018* Just thought I would provide another update and after 9 years my fields are still clear - I dump two gallons every six months into my last septic tank which gets pumped into the fields. (This is an updated review after 4 1/2 years - still using the product every 6 months and septic fields are still working great! As stated initially below, septic field failures are hard to diagnose. But once you get it cleared out, use this product to keep it clear.) It would be really hard to state that this item does or does not work. Septic field problems can be caused by so many different things as I have found out. When my fields failed, common sense told me that some liquid in a bottle was not going to fix my problem. I had my lines jetted first and then used a service that performs the "ground fracking" method to open clogged soil. Before they left they told me to use a product like this every 6 months to continually keep the soil conditioned. That was 2 1/2 years ago. My fields are still working and I cant tell for sure if this product works or doesn't. It was based on their recommendation. Since I haven't had any problems, I would say that it works. Most important thing I learned through this whole process - Do not run your water softener into your septic system!!! ## Frequently Bought Together - Septi-Flow Shock Septic Drainfield Repair Solution, Clears Leach Fields, Dissolves Hardened Deadpan Soil, Complete Treatment, One Gallon - 128 Fl Oz (Pack of 1) - Drain Field Treatment by Septi-Flow - Roebic K-570-Q 32-Ounce Leach And Drain Field Opener Concentrate - Environmentally Friendly and Biodegradable Solution - Septic Tank Treatment | Septic Enzyme Pods | 1 Year Supply | 2+ Billions CFUs per Pod | Fast-Dissolving, Live Bacteria-Plus Enzymes | Prevents Backups & Odors | Made in USA by Septi-Flow | 12 Packets --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/9033758-septi-flow-shock-drain-field-cleaner-and-leach-field-treatment](https://www.desertcart.us/products/9033758-septi-flow-shock-drain-field-cleaner-and-leach-field-treatment) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-29*
